rIhe object of my invention is to provide a simple and effectivepipe-wrench; and it consists in a straight metal bar whose upper end isforked to form two jaws, one ot' which is smooth and the other isprovided with two serrated steel cheeks projecting beyond the inner edgeof the jaw, whereby the pipe is held hetter and firmer, as will behereinafter more fully set forth.

The jaw B is smooth upon its innerface, while the jaw C is provided on each side with a steel cheek, D,having its inner edges formed with serrations d d, which project asuitable distance beyond the face of the jaw C, leaving a groove orconcave, e, be-

tween them. These cheeks D D are riveted .stituted with very littleexpense.
